Sheding during gestation

How many of you have had females shed during gestation. I have a female het albino who is now 66 days past her post-voulation slough. I looked on her last night and noticed her eyes clouding over. I have not observed my females shedding mid gestation too often, in fact, I only ever recall this once with a sonoran boa several years ago. Sadly I misplaced all my records when I moved country. So my question is this, how many of you have females that shed mid gestation.
